Answer:
Large expanses of land were opened by sealed-bid auctions after the allotment of lands to the various tribes, including the Kiowa-Comanche-Apache Reservation (1901), the Wichita-Caddo Reservation (1901), and the Big Pasture (1906). According to the Oklahoma Organic Act of May 2, 1890, the U.S. Congress added the Oklahoma Panhandle, or No Man's Land, to the new territory; parts of the Panhandle were already settled. Old Greer County, long in ownership dispute between Texas and Oklahoma, was awarded to Oklahoma Territory and opened to homesteading by virtue of U.S. Supreme Court order in United States v. Texas in 1896.
